Minimax at Data Centre World, Frankfurt, May 11–12, 2022

Coordinated Fire Protection Solutions for all Areas of Use

As recently as March, Minimax was named Vendor of the Year in the field of Physical Data Center Security by the trade journal LANline, thus repeating last year’s victory. And rightly so: The highly complex technical equipment of data centers and other IT areas, as well as the materials used there, incur a particularly high fire risk. A comprehensive fire protection system tailored to individual requirements ensures data availability and meets insurers’ requirements.

Besides gas extinguishing or oxygen reduction systems, water mist also plays a central role in data center fire protection due to its significantly lower water impact. That is why Minimax will be presenting the water mist applications together with its partner VID Firekill. Here, Minimax, together with VID Firekill, can offer solutions with FM approval.

If you wish to learn more about our special fire protection for data centers, or just want to hold the LANline award in your hand, we look forward to seeing you at booth A25.

Minimax Fire Solutions International at Securex Poland, Poznan, April 25-27, 2022

The largest event for the security industry in Central and Eastern Europe

After a forced break of two years, presence fairs are finally possible again, and Minimax is back. Impressive in its size and product diversity, the Securex International Security Fair presents a wide range of exhibits. Market leaders and internationally recognized companies from the security industry will be presenting their products and services. The focus is on innovative solutions for building security, software and systems that support security processes in various industries.

Minimax Fire Solutions International will be presenting next-generation fire protection in Hall 5A, Stand 55: The Minimax MXOne high-performance firefighting turbine enables the highly precise, targeted use of water mist from a safe and great distance. With full jet, it reaches a discharge range of up to 80m. The new development uses water mist, which absorbs a huge amount of energy, cools particularly effectively and reaches hidden fire sources due to the three-dimensional mode of action. Water mist binds smoke gas, pollutants and odors and can quickly develop its effect over large areas without, like classic monitors with their focused jets, dispersing burning material and possibly contributing to the spread of fire. 

The second focus will be on Minimax spark extinguishing systems. They protect wherever combustable materials are pneumatically transported. This is especially true for extraction and conveying equipment in the wood, textile and food industries. Ignition initials are already detected in the systems and automatically extinguished. Minimax is a pioneer in the development of spark extinguishing systems and offers them with VdS recognition as well as FM system recognition. The protection concept has been successfully proven in many thousands of applications worldwide.

Corrosion-Protection with Fendium: Polymer-enhanced pipes in Holtmeyer sawmill

Corrosive conditions exist in the pipe networks of water extinguishing systems. This not only causes pipes to rust but deposits also form that constrict pipes and clog sprinklers. The solution: polyme

Besides the obvious benefits of longer life and longer protection against rust-through, the polymer finish on the inside implies hydraulic advantages. Even after long-term use, the surfaces of Fendium pipes stay similarly smooth as those of plastic pipes and widely free of deposits that reduce the inside diameters. This means that the required water admission is not impaired by internal corrosion residues. This is why Heinrich Holtmeyer & Sohn Sägewerk und Holzhandlung GmbH decided to use Minimax Fendium pipes in the construction of a new sorting plant.

Fendium pipes offer an ideal combination of a longer service life, increased safety and greater efficiency: a sustainable concept!

Minimax Protects Deep-freeze Warehous of Coppenrath & Wiese

Sustainability in fire protection: Minimax has equipped Coppenrath & Wiese's deep-freeze warehouse in Osnabrück with a special oxygen reduction system: Minimax OXEO ECOPREVENT FC/VG.

The award-winning system generates nitrogen by means of a connected fuel cell. This solution is particularly economical: During power generation, the fuel cell produces clean, nitrogen-rich exhaust air as a by-product, which can be used for oxygen reduction. With this environmentally friendly solution, a return on investment can even be achieved, since the significant energy costs of the nitrogen generator that would otherwise be required are eliminated.

The Coppenrath & Wiese deep-freeze warehouse based in Osnabrück comprises 97,540 m3 in three protected areas. The temperature is around -22 °C. By introducing nitrogen, the oxygen concentration is reduced from 21% by volume (normal) to approx. 15% by volume and can still be accessed by verified personnel.

Saving up to 650 tons of CO2 annually
The fuel cell consistently delivers just under 100 kW of electricity (equivalent to 876,000 kWh/year) and just under 100 kW of thermal power, which the company uses to cover part of its energy load (electricity and heat). Whereas 132 kW was consumed with the old system, 86 kW of electricity is now generated on balance.

Minimax fire protection trough BWCon 1,400

Certified Fire Protection for IBCs and Storage of Flammable Liquids

When IBCs replaced traditional steel drums and metal tote tanks for transporting and storing highly flammable hazardous materials in the mid-1990s, a new set of fire risks emerged.

IBCs (Intermediate Bulk Container) are large cuboid containers for liquid and free-flowing substances. When they replaced traditional steel drums and metal tote tanks for transporting and storing highly flammable hazardous materials in the mid-1990s, a new set of fire risks emerged. John LeBlanc, Vice President and Senior Engineering Technical Specialist in FM Global's Chief Engineer's Group, recalls, “Suddenly, we jumped from 55 gallons in a steel drum to 275 gallons or more in a plastic container."

‘Unmanageable risk’
In the event of a fire, an IBC can melt, thereby leaking liquid. When an intermediate bulk container (IBC) filled with flammable liquid leaks, insurance companies refer to it as an ‘unmanageable risk’. With a filling volume of 1,000 liters, an area of about 330 m² would be covered with 3 mm of flammable liquid.

What complicates matters further is the fact that while the U.S. Department of Transportation (DOT) has approved IBCs for transporting flammable liquids, many assume that this approval also applies to storage.

U.S. property insurer FM Global, with its certification company FM Approvals, has addressed this issue and recently featured three products in IFP Magazine that significantly mitigate IBC fire hazards. Among them is the Minimax BWCon 1,400 FM fire protection trough that was certified by FM Approvals in 2018:

The Minimax fire protection trough is made of steel and has an integrated flame arrester. In the event of a fire, the burning liquid runs through this filter mat into the collection trough below. This combination prevents the uncontrollable spread of liquid and fire. The fire can then be extinguished, e.g. by a sprinkler system or the plant fire department, before the event develops into a major fire that threatens the existence of the plant. The tank has a total capacity of 1,400 liters. In addition to the 1,000 liters of flammable liquid from the IBC, another 400 liters of extinguishing agent can be held. This volume would be introduced by a sprinkler system during an approximate 20-minute period to extinguish the fire.

Besides the fire protection trough, FM Global certified the double-walled composite IBC from the German manufacturer Schütz in 2020 and the floor system from Houston, Texas-based Safespill back in 2017. The concept is derived from a drainage system used for helicopter landing pads in offshore oil platforms. In 2020, an enhanced version was certified for large applications such as aircraft hangars and distribution centers.

The recently introduced "LiquidProtect" sprinkler system from Minimax is not yet FM-approved but already recognized by VdS. It was developed specifically for the protection of flammable liquids in IBCs and drums stored in racks. Minimax thus provides an effective and reliable solution for the protection of flammable liquids.

Rich Ferron of FM Approvals sums up, “It has taken quite a while, but we now have FM-approved products that FM Global can recommend to its clients and that anyone in the world can purchase to address the very real fire risks associated with using IBCs in industry.”

Reusable cylinders for gas extinguishing systems
November 18, 2021 - Service

Sustainability at Minimax: Reusable Cylinders for Gas Extinguishing Systems

Minimax is now able to undertake the required container replacement for gas extinguishing systems with reusable cylinders.

Gas extinguishing systems ensure safety, even when they are not in use. Nowadays, however, numerous systems in Germany have exceeded the recommended maximum period of use, notably twenty years. Minimax sees a need for action.

First, the legal basis stems from the relevant regulations governing transportable gas cylinders (Ortsbewegliche Gasflaschen / Druckbehälter): TRBS 3145 / TRGS 745, DIN EN 1968:2002 + A1:2005, VdS 3159. Here, the recommendation is to replace a container after the double inspection period has expired, and an inspection and evaluation by the operator is required. The operator must decide, justify and document whether the containers should remain in service or not.

What many people do not know, however, is that gas-based extinguishing systems have to be regarded as work equipment, the regular inspection of which is specified in Art. 14 of the German Ordinance on Industrial Safety and Health (BetrSichV). This applies, in particular, to "longer periods of non-use". Where the quick-opening valves of the containers with extinguishing agent have not been operated since the filling process, the installer or the maintenance manager must assume that the effectiveness and reliability are no longer up to standard. In this case, the system operator and persons acting on their behalf are personally liable. A responsible operator will therefore replace the containers, as the safe use can no longer be guaranteed. Safety and care for employees are the top priorities here. After all, defective, outdated gas cylinders can become a safety hazard.

New: reusable cylinders
Minimax is now able to undertake the required container replacement for gas-based extinguishing systems with reusable cylinders. In terms of quality, there is no difference between new and refurbished containers. On the other hand, the economic and ecological advantages for operators are obvious: savings in terms of costs, efforts, and valuable resources.

Containers that have been removed are revamped by Minimax and subjected to a visual and pressure test as the basis for reapplying the inspection stamp. Primer and paint renewal are possible as is the modernization of the valve technology. Old tanks are returned to the material cycle.

Opportunity for modernization
Even though the main focus on cylinder replacement is on ensuring the availability of the system technology, replacing a container also provides an opportunity for modernization due to ongoing technological development.

Existing systems can be future-proofed without applying for new approval, for example, by switching from a mechanical to pneumatic actuating device. This makes future maintenance more efficient and leads to less downtime. Other advantages include the availability of spare parts with more modern technology and the ability to expand the systems with new technology. The need to replace an old time-delay device in low-pressure systems should also be given due consideration as should a potential reduction in space requirements by switching from carbon dioxide to nitrogen.

Thus, maintenance services can be combined with modernization. With the new reusable cylinders from Minimax, this can also be done sustainably and with a clear conscience.

Minimax Presents Fire Protection for Wind Turbines

At the on-site HUSUM Wind trade fair in Germany, Minimax will be presenting, until this coming Friday, its fire protection solutions that are tailored to the special requirements of wind turbines

The amount of renewable energy in electricity consumption is growing steadily: At 23.7%, wind energy provided the lion’s share of gross electricity consumption in Germany. Meanwhile, the hydrogen economy, along with wind energy – especially offshore wind energy – is gaining ground. For more than 20 years, Minimax has been protecting these indispensable energy suppliers with approved and certified fire protection technology – both onshore and offshore.

Early fire detection: Minimax aspirating smoke detector AMX4004
The core of reliable fire protection is the early detection of fire and combating it by applying a fire extinguishing process without delay. Our answer to ensuring this happens is the aspirating smoke detector AMX4004. It can withstand vibrations and high fluctuations in temperature as well as extreme climatic conditions. It detects fires as they arise by continually extracting air samples from the monitored area. In conjunction with intelligent evaluator algorithms, a comparison of typical disturbances takes place prior to setting off the alarm, meaning that the AMX4004 is extremely foolproof.

Fire detection and extinguishing control systems
The fire protection and extinguishing control systems from Minimax processes fire detection signals like those of the aspirating smoke detector AMX4004 or the flawlessly operating UniVario flame detectors using cutting-edge technology. They activate programmed control processes such as shutting down the wind turbine, notifying a constantly manned position as well as setting off the extinguishing systems.

Inert-gas extinguishing systems: environmentally friendly and no residue
The Minimax Oxeo Intergas extinguishing systems enable fire suppression adapted to sensitive and high-end facilities such as wind turbines. Inert gases are not electrically conductive and are non-toxic to humans, as they are a natural component of ambient air. They do not cool down and suppress fires without leaving a residue as well as being environmentally friendly. Normally, nitrogen is used in wind turbines but argon or mixed gases may also be used.

Water mist suppression systems: Minifog ProCon
Minifog water mist suppression systems reduce to a minimum the amount of water needed to combat fires. Special nozzles produce a very fine mist enabling the extinguishing agent to be distributed with a larger surface area: The ensuing cooling and suppression effect puts out any possible fire exceptionally quickly. Antifreeze in extinguishing water enables this method to be used at temperatures as low as –30 degrees Centigrade. The amount of extinguishing agent released is so small that normally no additional extinguishing agent retention devices are required. The extinguishing equipment, including the containers with the extinguishing agent for special applications, comes as a compact very lightweight unit that can be easily installed in the wind energy system.

New Fluorine-free Foam Extinguishing Agent

Minimax switches thyssenkrupp Steel Europe Fire Protection Systems to Fluorine-free Foam Concentrate

In May, Minimax and its competence team ‘Steel’ carried out a series of tests with fluorine-free foam concentrate at MPA Dresden GmbH, an independent fire protection competence center. The reason for the efficacy tests, which were supervised by VdS Schadenverhütung GmbH, was conducted at the request of our customer thyssenkrupp Steel Europe AG to convert its extinguishing systems to a fluorine-free extinguishing foam. All the tests were successful, and VdS approved the use of the new, 1% fluorine-free foam extinguishing agent for the protection areas and system types concerned. 

Legal background
Time is of the essence: On April 8, 2020, the EU Regulation 2020/784 was passed, further restricting the use of PFOA (perfluorooctanoic acid). Admittedly, firefighting foams are still considered to have a special status because every fire that can be prevented means that other, incalculable environmental damages are averted. The transitional period until July 4, 2025 still applies to fire extinguishing foams that are already filled in existing systems or mobile extinguishing equipment. From this date onwards, mixtures or products must not contain more than 25ppb (=μg/kg) of PFOA or a total of more than 1000ppb11 (=1ppm=1mg/kg) of all precursors. PFOA foams will no longer be allowed for educational purposes, and for testing only if there is a possibility of capturing all releases. As early as January 1, 2023, use will only be permitted at sites where all releases can be captured. 

What needs to be done?
As a result, many operators are concerned about the future of their fire protection facilities and would like to see a switch to fluorine-free foams. However, a number of requirements has to be considered in terms of the switchover: The VdS recognition for the use of foam extinguishing agents in water extinguishing systems according to VdS CEA 4001 and VdS 2109 always refers to the recognized foam agent and defined applications. If the intended area of application (type of system / fire load) is not already covered by the proof of effectiveness from the acceptance procedure, additional proof of efficacy needs to be provided. In this case, the foam concentrate was already certified for risks associated with plastics. The testing has since been carried out for certain flammable liquids. 

Tests
In May, Minimax conducted extinguishing tests for thyssenkrupp Steel Europe at MPA Dresden GmbH. The parties involved were VdS Schadenverhütung as the testing and certification institution, the risk manager, the foam agent manufacturer Dr. Sthamer, the operator, and Minimax with its competence team ‘Steel’ and the extinguishing system management ‘Water’. 

The configuration of the tests was prepared at length and tailored to the specific application. For the tests, Minimax installed both a deluge system and a water mist suppression system matching the real conditions of the existing system in terms of sprinklers, operating pressures and distances to the fire object. The extinguishing of three selected flammable liquids was tested, each using water and foam extinguishing agents. 

Successful result
The effort was worthwhile: VdS approved the tested foam agent for use in the given types of systems in combination with the three examined flammable (hydraulic) liquids and for use in accordance with the protection concept as per VdS CEA 4001 (sprinkler systems), VdS 2109 (deluge systems) and VdS 2108 (low expansion foam extinguishing systems). 

For Marcel Esper, Head of the Minimax competence team ‘Steel’, and Thorsten Gieseke, Minimax suppression system manager, the results of the extensive extinguishing tests are even more far-reaching: "Beyond the approval, we gained a lot of additional knowledge that we will take into account for the further procedure with fluorine-free foam agents." The competence team ‘Steel’ is the specialist for stationary fire protection in the steel industry, providing single-source support in the Ruhr region for the plants of thyssenkrupp Steel Europe AG, among others. 

For thyssenkrupp Steel Europe AG, the switch to fluorine-free foam concentrate is a particular concern, both to ensure fire protection and, at the same time, to contribute even more to environmental and water protection. The fact that this can be achieved with comparatively little effort means enormous potential savings for the customer. Converting the plant would incur costs and, on the other hand, production would be impaired during conversion periods.
